Application `filed August 2, 1919. lSerial No. 314,911.'

To all whom t 'muy concern Be it known that I, -WALTER J. LEVERIDCE, a subject of the King of Great Britain, residing at Mount Vernon, V`in the county of Westchester, State of New York, have invented certain new and useful' Improvements in Vacuum-Tube Holders, of which the following is a full, clear, concise, and eX- act description.

yThis invention relates .to vacuum tubes and more particularly it relates to a holder for such tubes.

In the manufacture of vacuum tubes, particularly of the type comprisingmore than one electrode, it has been found convenient to subject the electrodes of the tubes to electrical tests previous tothe final mounting of the glass tube in its collar or shell on which are provided terminal lugs for the lead-in wires of the various electrodes of4 the tube.

An Object of the invention is to provide a holder for unmounted vacuum tubesv so that they may readily be connected in a circuit for any electrical tests desired.

The holder provided according to this invention comprises in its preferred form a block preferably of insulating material, on one side of which is a collar on which are mounted terminal lugs which, are adapted to coperate with spring clips or other form of contacts in a base'or socket .adapted to receive the collar. Preferably there should be as many lugs as there are lead-in wires for the vessel to be held. On the other side of the block are mounted a plurality of spring clips between which the glass bulb may be securely held. Projecting from the same side ofthe block are a plurality of binding posts which are of a suiiicient length to enable the lead-in wires of the tube to be readily and conveniently fastened thereto. Each postl is electrically connected to one of the lugs mounted on the collar. When, therefore, it is desired to test an unmounted vacuum tube, the tubev is .inserted between the spring clips and each -lead-in wire is fastened to the proper binding post. The collar may then be inserted in a suitable socket which is connected to the electrical apparatus necessary to perform the testing.

This invention will be -better understood by reference to the following detailed decom'panying drawing which re vSerial No. 98,7 7 0, filed scription taken 'in vconnection with lthe acpresents the preferred form o'f this inventio Referring to thedrawing, 5 is a block ofv insulating material on one side of which are mounted a plurality of spring clips 6, 7, 8

and 9,. which are adapted to hold securely" the glass bulb 10 of a vacuum tube. Pro- ]ecting from the block 5, are also a plurality of binding posts 12 13, 14 and 15, each of which is provided with a spring 17 and a washer 18, whereby the lead-in wires may bev electrically connected to the binding posts 1n a convenient manner.

Mounted on the opposite side of block 5 lsa collar 25 from which project the termmal lugs 26,27, 28, 29. `Each of these lugs lis electrically .connected to' one of the binding posts by electrical connections located 1n the grooves 30 in the top of block 5. The collar 25 which is preferably-of the type used on (the -vacuum tubes designed to be held by the spring clips of the holder,

.is adapted to be inserted in a socket which scribed and'claimed in a patentappli'cation to Shreeve, Serial No. ruary 20, 19.18.

It is to be understood that the vacuum tube holder of this invention is not limited to the particular form described above, but it may be variously' modified without departing in any wise from-the spirit of this invention as defined in the appended claims.

What is claimed is:

1. A holder` for a vacuum tube comprising a block, means for holding said vacuum tube, binding posts on said'block, and terminal lugs on said block electrically connected to said binding posts.

2. A holder for a vacuum tube comprising ablock, spring tube-engaging fingers on said block, binding posts on said block, and

218,254, med Febjecting from said block in the same direc-V -tion as said fingers, and terminal connections for said holder on the side of said block opposlte said fingers,I said terminal connections being electrically connected to said binding posts.

4. A holder for a vacuum tube comprising a block, spring tube-engaging fingers projecting from said block, binding posts vprojecting from said block in the same direction as said fingers, a vacuum tube collar on the side of said block opposite said fingers, and terminal connections for said holder comprising a plurality of lugs projecting from said collar, said lugs being electrically connected to said posts.

5. A holder fora vacuum tube comprising a block, spring tube-engaging fingers projecting from said block, binding'l posts projecting from said block in the same direction as said lingers and corresponding in' number to the number of lead-in Wires possessed by the tube to be held, a collar ontlie side of said block opposite said lingers, and terminal connections for said holder comprising a plurality of lugs projecting from said collar, said lugs being directly connected to said binding posts and corresponding in number to the number of lead-in Wires. possessed by the tubje to be held.

6. A holder for a vacuum tube comprising a block of insulating material, spring tube-engaging fingers projecting from said block, binding posts projecting Jfrom said block in the same direction as said fingers of lead-in wires possessed by the tube to be held, Wire-fastening-means on the ends of said posts, a vacuum tube collar on the side of said block opposite said fingers, terminal connections yfor said holder comprising a plurality of lugs projecting from said collar, and an electrical connection between each of said lugs and one of said binding posts, said lugs corresponding in number to the number plflliead-in wires possessed by the tube to be -7. A holder for a Vacuum tube comprising terminal lugs, members contacting with s aid tube for positioning said tube with respect to said lugs, and a plurality of rigid electrical connectors extending from points adjacent the base of said tube in the direction of said lugs.

In witness whereof1 hereunto subscribe my name this 28th day of July, A. D. 1919.
